Abstract:

The vertical dynamic behaviour of machine foundations subjected to vertical dynamic loading was investigated for surface and embedded foundations. The responses of these machine foundations were determined using analytical and numerical solutions ranging from simple to complex. An accurate prediction of impedance functions for the foundation system is a key step in the design procedures. The prediction accuracy depends on how close the modelling procedures are to reality. The subject of soil dynamics is complex. At times, the choice of the analysis model is based on the experience of the

De nos jours, les exigences de productivité et de maîtrise des coûts ont incité les industriels à développer de nouvelles machines, et avec elles, de nouveaux enjeux sont apparus : souplesse de la structure, vibration, effets dynamiques non-négligeables, etc. Pourtant, leur mise en œuvre est toujours issue de méthodes employées pour les machines conventionnelles. Ces travaux s’intéressent donc à la définition de stratégies globales englobant la prise en compte de la structure utilisée et de la tâche à réaliser, appliquée à deux contextes d’illustration.

Abstract:

The loading problem in a Flexible Manufacturing System (FMS) lies in the allocation of operations and associated cutting tools to machines for a given set of parts subject to capacity constraints. This dissertation proposes a hierarchical approach to the machine loading problem when the workload and tool magazine capacity of each machine are restrained. This hierarchical approach reduces the maximum workload of the machines by partially grouping them. This research deals with situations where different groups of machines performing the same operation require different processing times and thi

Abstract:

Flexible manufacturing systems (FMS) have received increasing attention from researchers and practitioners due to their potential advantages: quicker response to market changes, reduction in work-in-process (WIP), high inventory turnover and high levels of productivity. Two groups of problems in an FMS are of importance: (1) design problems and (2) operational problems. Operational problems can be effectively separated into 4 sub-problems: planning, grouping, machine loading problem (MLP) and scheduling.

Abstract:

This thesis describes new methods of evaluating the efficiency of three-phase induction machines using synthetic loading. Synthetic loading causes the induction machine to draw full-load current without the need to connect a mechanical load to the machine's drive shaft. The synthetic loading methods cause the machine to periodically accelerate and decelerate, producing an alternating motor-generator action. This action causes the machine, on average over each synthetic loading cycle, to operate at rated rms current, rated rms voltage and full-load speed, thereby producing rated copper losses,

This thesis investigates the application of the synthetic loading technique for efficiency evaluation, of permanent magnet (PM) synchronous machines. The standard tests require specialist test facilities, additional machines, and for large machines, linear machines, or vertical mounted machine and floor space. Therefore, an efficiency test method that avoids the need for an external mechanical load is desirable. Synthetic loading can determine machine losses and eliminates the need for a mechanical load connected to the test machine. The synthetic loading technique forces the machine under tes

This improved model gives a better representation of the frequency dependency of the fluid-loading coefficients: this is particularly important in compliant motion

碩士<br>國立彰化師範大學<br>電機工程學系<br>98<br>ABSTRACT This thesis designs a vertical loading work-piece mechanism with two axes controlled by servo motors. Due to imperfect rigidity, shock will occur under different speeds and loading weights. In order to meet the accurate position of automatically changing work-piece in different operating speeds and loading weights, back propagation network (BPN) is applied to search the best proportion gain P K of the servo motor controller. Operation speeds and work-piece weights are the variables of input layer of BPN. There are twenty nodes in the hide layer, and o

Abstract:

M.Tech. (Mechanical and Industrial Engineering Technology)<br>Small scale farmers often lack the financial resources to purchase the necessary agricultural machinery to make their work easier and more efficient. Consequently they have to employ labourers to do the work manually, work that could otherwise be done by a machine faster and at a lower production cost. The majority of the existing agricultural machinery on the market is designed for large industrial scale farming and is unaffordable to the small scale farmer. After a small scale farming survey, it was found that there is an acute ne

碩士<br>國立臺北科技大學<br>資訊與運籌管理研究所<br>100<br>Flexible manufacturing systems ( FMSs ) are defined as collections of computer numerically controlled ( CNC ) machines and automated material handling mechanisms. We assume that each operation can be allocated to only one machine. We aim to assign operations to machines and allocate machine capacities in order to maximize the total weights of completed operations. We introduce a workload balancing constraint. Our model not only maximizes the throughput but also tries to smooth machine loading. We use the CPLEX mathematical programming method to fi

碩士<br>國立交通大學<br>管理學院工業工程與管理學程<br>102<br>This research studies the daily job release policy for a semiconductor wafer fab, operating in a scenario which involves both MTO (make-to-order) and MTS (make-to-stock) orders. The objective of the job release policy is to minimize the work-in-process (WIP) deviation of the bottleneck workstation, in order to reduce the deviation of cycle time. Four heuristic methods (M-1, M-2, M-3, and M-4) are developed in this study and justified by a simulation program coded in Flexsim (proprietary discrete event simulation software). Simulation results indicate tha

In recent years, it is widely used in the family and the gymnasium. Therefore, it is necessary for further discussion about the movements of the elliptical machine, and various levels of the lower-limb muscular fatigue using the elliptical machine in various strengths. The research collected the electromyography (EMG) signal of lower limb muscles, and used the commercially available software to analyze the possible timing that the fatigue appeared. Th

Hence, the requirements for high machining precision gain a lot of intentions by the customers and machine makers. To improve the precision of machine tool, most companies have made their efforts on developing new model or doing optimization design on their origin designs. One of the key issues that cause the precision problem is the displacement between the spindle head and the platform. The relative displacement between the spindle

Since the regulation of labor safety and health has requested employer to introduce the machinery safety regulation into purchasing standard, and employer only use domestic standards and parts of CNS as safety regulation. Therefore, by analyzing the “dense unpack machine” in some TFT-LCD companies as a case to study the adaption of international regulations introducing into domestic regulation
